Abstract

PURPOSE:To prevent a noise due to the ON/OFF of a current from being generated and to eliminate power loss in a power switching circuit, etc., by controlling a generating power by charging an operating frequency by a detected temperature. CONSTITUTION:The operating frequency fs outputted from a selector 9 is supplied to a computer system 1, and executes a program with a low frequency at a high temperature and with a high frequency at a low temperature. Thus, a power control circuit 14 accelerates processing speed, that is, a throughput by raising the operating frequency fs by utilizing the allowance of the temperature if it exists. In case of the high temperature, a processing to suppress the generating power is performed by lowering the operating frequency fs and decreasing the processing speed to lower the temperature. In such a way, it is possible to eliminate the noise and the power loss in the power switching circuit due to the change of the current.
